MFJ-917, BAL. LINE ADAPTOR, BAL TO UNBAL, 1.8-30MHz.

The MFJ 1:1 Current Balun is enclosed in schedule 40 PVC pipe for maximum strength and protection. Unlike other baluns, the MFJ-918 makes a direct electrical connection to the antenna with #14 copper wire. The MFJ Current Balun will reduce or …

The MFJ-919 is a 1500 Watt true current baluns/antenna center insulators that transforms 200 ohms to 50 ohms. Transmission Line Transformer construction using 100 ohm characteristic impedance transmission line gives flat 160-10 Meter response. Large low permeability ferrite cores easily handle full power. SO-239,

2014年10月23日 · The MFJ-919 is a 1500 Watt true current baluns/antenna center insulators that transforms 200 ohms to 50 ohms. Transmission Line Transformer construction using 100 ohm characteristic impedance transmission line gives flat 160-10 Meter response.

MFJ 4:1 current baluns are designed to replace the center insulator of a dipole antenna. They are made up of two large low-permeability ferrite cores. The MFJ-913 is rated at 300 watts and the MFJ-919 is rated at 1500 watts. Their SO-239 coax connectors have TeflonTM internal insulation for maximum insulation and extended life of the product.

MFJ-912 converts unbalanced coax to balanced transmission line (ladder). Giant 2-core 4:1 balun wound with Teflon wire connects to high voltage ceramic feedthru insulators. Handles full legal limit with ease. SO-239 connector. Use coax from antenna tuner to MFJ-912 mounted outside.

The MFJ-918BP is a 1:1 Currnet Balun, specified for use between 1.8 and 30 MHz. It's housed in a heavy-duty weather protected PVC housing., and it utilizes red and black 5-way binding posts and a Teflon-dielectric SO-239 connector. Dimensions: 2" dia. x 6" length.
